A clean duster/cloth should be sufficient to lift finger marks, guitar polish for a deeper clean but spray it onto the cloth not the guitar and keep it clear of the strings. If you have no guitar polish use a polish specially for wooden furniture but use sparingly. Always use clean cloths or dusters in case they have been use with any other cleaning products.
You should clean your guitar fretboard with a soft cloth slightly dampened with water or a specialized guitar fretboard cleaner. Avoid using harsh chemicals or excessive moisture to prevent damage to the wood.
No, but you should be very careful to only use it on the strings, and not on the body of the guitar.

To maintain the sound quality of your guitar, regularly clean the strings with a soft cloth to remove dirt and oils that can affect the tone. This will help preserve the brightness and clarity of the sound produced by your guitar.
